To all whom 'it may concern: y

Be it known that I, HOWARD M. DLUDLEY, a 1citizen `of theUnited States, and a resident of Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in DyeingMachines, of which the following is a specification.

My invention relates to dyeing machines and refers `particularly to those machines in which textile fibers are dyed under compression, the dye liquor being forced through the compressed mass. i,

The dyeing of fibers under these conditions presents many difficulties, asit is essential that all parts of the `fiber mass be treated absolutely equally by the dye liquor, as otherwise uneven results will be obtained.

This equal treatment `is dependent upona number of conditions; the liber must be uniformly `and properly compressed, the liquor must `be at a uniform pressure throughout the ber mass, the formation of channels or passages within the ber `mass must be avoided,the dye liquor must be of such dilution as to prevent precipitation upon the fiber, the temperature of the liquor must be properly retained andmeans must beemployed for determining the condition of the dyed `fibers `without interruptin the dyeing operation, opening the dyeing c amber or disturbing or sampling the fiber being dyed. l i

The device of my invention accomplishes all of the above results in a manner economical in construction and cheap, simple, accurate and positive in operation and possesses other `advantages which will be evi? dent upon a consideration `of my speciication, drawings and claims. i

As a means for preserving uniform pressurethroughout-the fiber mass, preventing the formation offchannels andfcausing an even anduniform distributioinof the" dye liquor, Iinclose the compressed fiber between two forarninous plates, the plates beingfeomposedo'f parallel upwardly anddownwardly extendedmembers, having openings to allow of the passage" lof the liquor. Inorder to obtain a uniformly` distributed pressure againstthe faces of the foraminous plates, I introduce al curved tubular liquid-supply membervthrough: which theliquid is l forced, said liquid supplyrnembe having Within ita series of curved tubular members so shaped and arranged as to impingethe liquid equally and uniformly upon the faces of the plates. i l

In orderto obtain a still further distribution of the liquid through theber mass, I employ means whereby the liquid may be passed through the mass in opposite directions as desired. l i l In order to judge of the condition of the fiber, I have a small dyeing device exactly similar and proportionate to the larger device and so constructed that ber inserted therein will receive exactly the same treatment as `that in the larger device, the same proportionate amount of the same liquor passing through both under the same pressure and temperature, so that in `order to determine the condition of the dyeing, the operation in the large device need not be even interrupted, the large device neednot be` opened, and it will not be necessary to disturb the fiber contained therein.l i i I also employmeans whereby the top of the dyeing receptacle may be readily removed; to `.allow of the `loading andunloading ofthereceptacle. i i l i y l .In` the drawings, illustrating` modified forms of the device of my invention, simi i larparts are designated by similar numerals.

`fied form of a foraminous member of a foliig.` `6 is a top-plan view of one of the The device ot my invention illustrated in the drawings, comprises a receptacle having bolts 25, 25; and the upper extremities ofy lthe sides are attached to the upper liquidsupply member 26 by means of the bolts 27,

27. The lower liquid-supply member 24 has the valve 28 and is att-ached tothe tubular' y member 29 by means ot the bolts 30, 30. f The member 29" carries the pipe 31 attached toQtlr-e delii'feriirgpipe 32" ot' the pump 33. The receiving side` of the pump 33" is connected ,to the pipe 34 which in turn is connected to thethree-way pipe coupling 35. Thepipe coupling-35 is connected to the' pipe 36 eonnectedto a source of liquid sup# ply-vr (not shown) and carryingthe valve 37. The pipe couplingV 35 is also Connected to the pipe 38, havingthe valve 39, the' other end' of the pipef38 being connected tothe lower extremity of a liquidisupply tank 40. The upper liquid supply member 26 con'- verges outwardlyand then downwardly into the tubular member 41 carrying the valve 42, the member 41 entering the tubular' member 29 and being connected thereto by means of the ball socket 43. The uppei liquid sup-A ply member 26 contains a'series' ot outwardly converging curved hollow members 44, 44,

. extending from'the lower plane ofthe member 26 toward the sn'iallest `end of said member 26; and thelower liquid-si'ipply memberv 24 contains a series of similar hollow members 45, 45.` f Y VVithiir the# receptacle and extending` across the same are a seriesof Vtoraminous plates. vSiti'iated above the lower extremities of the sides 20, 21, 22, 23, is foraminous plate 50 comprising av series of parallel serrated upwardly extended' plates 51. Spaced above the foraminous plate 50 is a forami-V nous plate 52V comprised offa series of parallei members -consisting of upwardly extended triangular members 53, 53, situated Varound circular openings 54, 54.` Slidable within the vreceptacle is argtoraminous plate silnilar inconstruction to the `plate 52, the triangular members 53, 53 extending downwardly'. Spaced above' thel fora-minous plate 55 is the foraminous'plate'56' having a Y `downwafrdljy extended ganiiular Ymem-ber 57, Y capable otfabu'tment upon/the upper surface of the plate 55. An: angular annular mem# v ber 58 is capable of 'abutmentv uponlth'e upper tace of the plate 56, and is eapableo being moved! downwardly within the receptacle and upon the plate 56 by means of the ,screw bolts 59, 59, threaded throughl the member 58, and the' annular extension 60 ofthevsides of vthereceptacle.r pipe 61, vcarrying the valve 62 is connected with the receptacleVv abovethe plate and opens,intoftlieupper4 Aportion'ott-lief Vli'lofiid reserv? tank 40. The

pipe 61 is connected with the pipe 63, having the valve 64, which 1n turn is connected with the receptacle below the plate 52.

, A perforated steam pipe is introduced 82 are the pipes 85 and 86 having respectively the valves 83 and 84,y closeen'gagement between the conduits and the pipes being formed by the bushings 87, 87. The testing device 81 has annular members 88, 88 at each end thereof. Unions 89, 89 threaded upon the interior ends of pipes 85, 86`hold the testing device 81 in position. The testing device 81 contains foraminous plates and a liber carrying chamber similar' to those in the larger device.

In the oraminous member of the foruminous plate shown' in Figs. 10 and 11, the extended members 53, 53 are situated around a rectangular opening 54, the toraminous plate comprising a series of such elements'.

' The operation of the device is as follows:

vThe topy 296 is revolved into the Aposition shown the dotted lines' 26A ofFig. 3,' thus opening the receptacle. The annular mem ber 58 and the foraminous plates 56 and 55' are removed The liber' 100 is then placed within the receptacle`- and upon the plate 52. The plates 55 and56and the member 58 are then introduced vinto the receptacle and pressedV downwardly by'mea'ns of the screw bolts 59j, 59. Thel top 26 is then revolved over the top of the receptacle and clamped thereto by means of the screw bolts 27, 27. The testing device 81 is removed, packed with the fiber and replaced. All of the valves are closed with the exception of valves 37, 28, 62, 83 and 84. The pump 33 is then started, forcing' the liquid from thev tion the liquid is also forced through the conduit 80, the testing' device 81 and the conduit 82',`

From time to time, desired, the flow of the liquid ris reversed by closingall of' the valves' with' the exception of valves 42, et

and 39, thus giving the liquid a downward circulation through the device.

When it is `desired to wash theii'ber, the

dye liquor is removed from the device, the

valve 72 opened and fresh waterdelivered by means of the pipe 71 to the pump 33 from whence it is forced through the device.

\ W hen it is desired to determine the condition of thefi'ber 100, the valves 83, 84 are closed, the testing device SIremoved and the contentsexamined, this operation being capable of performance Without interrupting the operation of the larger device.
